FASTENER FOR THE MEETING-RAILS OF SASHES.

SPECIFICATION forming part of Letters Patent No. 389,213, datedSeptember 11. 1888.

Application filed December 7, 1887. Serial No. 257,182. (No model.)

To all whom it may concern.-

Be it known that I, GILBERT B. FRENCH, of Lynn, in the county of Essexand Commonwealth of Massachusetts, have invented certain Improvements inDevices for Fastening \Vindow-Sashes, of which the following, taken inconnection with the accompanying drawinggs, is a specification.

This invention relates to that class of de vices commonly placed at thetop of the bottom window-sash and used for locking the sash in a closedposition.

It is the object of this invention to provide means whereby the deviceis prevented from marring the top of the window-casing when the sash islifted to its extreme height.

The invention consists in combining with the fastening device a flexiblebunter, which, coming in contact with the windowcasingarrests the upwardprogress of the sash, and itself yields under the accompanying pressure,so as not to mar the casing.

Referring to the drawings,Figure 1 is aplan view ofawindow-fasteningdevice constructed in accordancewith and embodying this invention. Fig.2 is alongitudinal vertical section on line 2 2. Fig. 3 is a perspectiveView of the bunter detached.

The plate A is provided with suitable holes, a a, adapted for screws.The plate is designed to bear upon the top part of the bottom-sash, andis firmly secured to the sash by the screws passing through said holesand fixing into the sash. Said plate A is provided with a curvededge-face, e, adapted to engage a boss, f, on the lever H. Said leverhas its rear end pivoted to a mechanism fastened upon the bottom part orback sash, and is adapted to permit a horizontal swinging movement, tothe end that the lever may be brought round in front of the edge 0 ofthe plate A, as represented in Fig. 2. All this mechanism is common, andthe arrangement thereof is Well known, and its operation is understood.

The plate A is provided with an opening to receive the bunter B. Saidbunter is represented in perspective in Fig. 3. It is preferablycomposed of'soft rubber, and is given the form represented in saidfigure. In use, the bottom face of the bunter bears upon the window-sashand is held thereon by the plate A, (represented in Fig. 2.) The plateand bunter have their contiguous faces beveled,as shown, to prevent thebunter fromlifting out of place, and also to insure its solid connectionwith the sash. The top or body portion of the bunter extends upward andterminates at somewhat above the highest part of the plate A, to the endthat when the window is lifted the bunter may first come in contact withthe casing and yield sufficiently to prevent the marring of the same,and yet arrest the upward progress before the hard edges of the platecome against it.

Having thus described my invention, I claim as new and desire by LettersPatent to secure 1. In combination with a window sash locking mechanism,the flexible bunter B, said bunter being extended above the rigid facesof the locking mechanisnnsubstantially as and for the purposesdescribed.

2. In a window-locking mechanism,the combination of plate A and bunterB, having their contiguous faces beveled, substantially as described andshown.
